They were accompanied by some Indians, who were skilful divers, and could go down a great way into the depths of the sea.
The boat's crew proceeded to the reef of rocks, and rowed round and round it a great many times.

They gazed down into the water, which was so transparent that it seemed as if they could have seen the gold and silver at the bottom, had there been any of those precious metals there.
Nothing, however, could they see, nothing more valuable than a curious sea shrub, which was growing beneath the water, in a crevice of the reef of rocks.

It flaunted to and fro with the swell and reflux of the waves, and looked as bright and beautiful as if its leaves were gold.
"We won't go back empty-handed," cried an English sailor; and then he spoke to one of the Indian divers.

"Dive down and bring me that pretty sea shrub there.

That's the only treasure we shall find." Down plunged the diver, and soon rose dripping from the water, holding the sea shrub in his hand.
